Exercise makes everything better, improves all outcomes.

We've seen in the exercise oncology field.

We didn't get a chance to discuss it, but there's a few preclinical animal models showing that exercise makes some tumors grow more quickly.

So it's not this panacea for every single tumor.

In general, it slows the growth and spread, but we've seen a few publications showing the mice that exercise, the tumors grow more quickly.

We've also seen a few studies, including a couple of my own, showing exercise exacerbating symptoms in cancer patients.

So in one of our studies in rectal cancer patients, it looked like the exercise intervention made skin irritation from radiation worse.

exercise making skin irritation worse.

It looks like it made diarrhea worse in these patients.

Hand-foot syndrome, which is sort of a peeling and tenderness in the feet and hands.

You can imagine walking on a treadmill or lifting weights.

And in a couple studies, it's shown it's made fatigue worse.

So there are these, you know, we have to be very careful about exercise will benefit everything, cure everything, and make everything better.

And

I'll end off.

There is one cancer, we talked about prevention, that exercise increases the risk of cancer, and I suspect you can probably guess it.

Skin cancer.

So very compelling.

Correct.

So, well, it's misleading in one sense, yeah.
